OFFICE- f CHECK PRINTINGMECHANISM FOR CASH REGISTERS AugustRadermacher and Heinrich Bruckmann,I-Essen', .Germany, assignors to Fried. Krupp Aktiengesellschaft,Essen-on-the-Ruhr, Germany Application May 6, 1927 Serial No. 189,373,and in Germany July6, 1926 20 Claims." (01. 235-3) The invention relatesto a printing mechanism for cash registers which is adapted to issue aplurality of checks in one cash operation.

Printing mechanisms are alreadyknown which permit a plurality ofentirely equal checks to be.

issued. It may, however, be desirable to. issue either one check only orno check at all instead of a plurality thereof. It may further bedesirable to characterize in different manner several checks issued inone cash operation and showing the same record. Finally, it may beadvantageous, if a plurality of checks are issued in one cash operation.to have them of different length in order to have space on one of themfor handwritten records which are not required with the other check. Theobject of our invention is to fulfil these conditions. I

In order that our invention may be more easily understood, a preferredembodiment of the same is illustrated in the drawings which accompanyand form part of this specification. In these drawings:

Fig. 1 is an end view of the printing mechanism constructed according toour invention,

Fig. 2 is a lateral view thereof, V Fig. 3 is a section showing thearrangement of the platen,

Fig. 4 shows the arrangement of the check counter,

Fig. 5 shows two checks issued in one cash operation,

Fig. 6 is a single check as issued. I r The type wheels forming the mainprintin drum 1, see Figs. 2 and 3, are set in the wellknown manner fromthe differential mechanism of the machine. The platen 2 and knife 3 aremounted on a vertically guided common carrier 4 which is actuatedbymeans of a two-armed lever 5, 6 from the curved disk '7 serving for onetime inking and two times printing and cutting The curved disk '7. islooselymounted on the eccentric portion 8 of a shaft 9. This eccentricportion further carries a rubber drum 10, see Fig.f

2, adapted to co-operate, when in operative position, with two feed camsll and- 12 of different length of a feed and date drum 13. The lattercomprises date and numeral type wheels 14 and an engraving 15 such asforimpressing bufietj which appearsin dotted linesbehind cam l1 in Fig. 2,the wheels 14 and engravinglfilikewise co-operating with the rubber drum10. v A lever consisting of two arms 16 and 17, rigid to shaft 9.

' joined at its upper end to arm 20 and engaging a pin 17a of arm 17 bya groove therein at its lower end- [The latter is acted upon by a spring21' and held in position of rest by a pin 22. In this position theeccentric 8 holds the rubber drum 10 and the curved disk 7 in operativeposition, Fig. 2. The rocker 20 can be rocked upward by the depressionof a key W whereby theeccentric 8 is turned clockwise and the rubberdrum 10 is brought out of ready position. This motion of the eccentric 8further causes the curved disk 7 to come into apositiori in which theliftingmo tion of platen 2 and knife 3 is less than normal and thusinoperative, Hence, if key W has been depressed, neither a feed motiontakes place nor a check is printed and issued nor the types are inked oran impressio'niis made on the rubber 24, such as for printing the wordkitchen. 2 Both said date drums.13 and 23 have imparted to them onecomplete revolution from the pinion 26,

Fig. 1, by means of pinions 25. Pinion 25 of feed drum 13 is engaged bya pinion. 27, of equal size, Fig. 1, which is rigidly connected to thecurved disk 7 and remains in mesh with pinion 25 even if disk 7 isrocked.

A n eccentrically mounted rubber drum 28, Fig. 2, is adapted toco-operate with the date drum 23. An arm 29fast on the shaft 30 of saidrubber drum 28 is hinged to an arm 32 of a rocker 33 by means of a rod31.- The rocker 33 is held in q position of rest by spring 21' and abutsin this i position on pin 22. p In thisposition shaft 30 holds therubber drum 28'out of ready position, see Fig. 2. Arm 32 is' furtherconnected by a rod 34 to a rpitman 35 which embraces the axle 35' with aslot and is rocked about this axle when arm 32 is rocked. A roller 37.of 'pitman 35 co-j operates with a cam disk 39 under .th-action' of aspring 38. In the position of rest, Fig. 2, the

lower end of pitman 35 engages under arm 16 of shaft 9 by means of a pin40.

By depressing key Sp the rocker 33 is lowered and arm 32 is rockedclockwise. When this takes place, rod 31 rocks arm 29 of shaft 30counter-clockwise whereby rubber drum 2% is brought into ready position.Furthermore, rod 34 rocks pitman 35 clockwise about axle 36 whereby pinis swung out of the range of arm 16 so that in one revolution of thecurved disk '7 in the cash operation the arm 16 is not acted upon andrubber drum 10 and curved disk 7 remain in ready position. Hence, whenkey Sp has been depressed, the check strip receives,

upon the first feed motion caused by cam 11,

from the date drums 13 and 23 on two places first an impression showingdate and number, the first of these impressions further containing fromthe engraving l5 theword buffet whilst the second impression still showsthe word kitchen from engraving 24. The setting of a type wheel mountedon the same ,axle as the amount type wheels 1 and having the types W, G,and Sp may be effected in a manner well known in the cash register artaccording to one 01 thelkeys W, G, or Sp depressed; as is illustrated bythe setting of the sellers type wheel in the patent to Breitling, No. 1,49,443, Nov.

15,1927. AIter the first feed motion the first impression of theenteredjamountjtakes place and of the character Spby means of .platen 2,and the first check showing the impression Bufiet is cutoff, Fig; 5. Dueto thegreater length of the second check a space for hand-writ:

- ten records is offered thereon.

A-third key denoted 'on'its knob by is provided besides keys W andSp,'but does not 00- operatewith'eitheroi the rockers 20, 33. There:

fore, upon depressing key G the machine is released with'both rubberdrums 10; 28 remaining in normal position, more particularly, drum 10and with it curved disk 7 remain in operative position, and drum 28 outof operative position.

In the subsequent cash operation therefore only the 'datedlum 13executes an impression'with the first feed motion. Then the impressionof the set amount and of the character G takes place in a conventionalmanner by means of platen 2 and the check is cut off Fig. 6, platenand'knife being operated by cam 7 over leverfi and "car-.

rier 4. Before -"the second feedcam 12 has 91- rived at the rubber drum'10, pitman 35 israised by' the cam disk. 39 acting upon roller 37,arrnj 16 is engaged by pin 40 and so rocked that rubber; drum 10 andcurved disk 'l coineout'of operative range. ..When this takes placapin 1g travels'in a slot' l'lb of -rod 18 without acting upon this rod; 1 -'Aspring 170 tends to return lever l6 to itsnormal positionas' 'shown'inFig. 21'" Whenj key G is depressed, feed-motion for and] im prestakeplace sion on a second check thus do not and one check only is-issued.

"The specific manner of unlocking-the drive shaft-for the operation of amachinecycle by the actuation of any oneof' the three keys does notconstitute a feature of this invention? It may be difierently. inked.This permits the issuance of two checks in one cash operation eachhaving a' differently colored impression.

To feed the consecutive numbersin the chec counter of the two datedrums, an actuator 43,

Fig. 4, is provided, the tongues 44 and 45 of which co-operate with thetwo feed wheels 46 and 47 of the check counters. An arm 48 is rockablymounted below another tongue 52 of actuator 43, and is provided with apin 51 engaging in a slot in the lower extension of rod 18. Upwardmotion of rod 18 causes a clockwise rocking of arm 48 which swingstongues 44 and 45 out of the path of thefeed wheels 46 and 47. When keyW is depressed, any counting motion of the two check counters does nottake place, liwhilst with the keys G or Sp depressed, the feed motion ofwheels 46 and 47 takes place in common. I

' In the embodiment hereinbefore described two secondary printingmembers are provided for, viz. the two date drums, one of which forms atthe same timea feed drum, while both drums carry different engravings.The invention may be employed, however, also in a printing mechanismhaving no date drum and in which date and l nurnber is printed in oneline by the types set by the machine. If no date drum is provided for,the two secondary printing members (engravings 15 and 24) are arrangedon the drum 13 which in this case serves to feed motion only. If thesecond date drumis' omitted, also its companion drum 28 and thrust rod31 are unnecessary. 3

To summarize the operation of the 'machine: The-'machine is normally setto issue a single check of the type illustrated in Fig. 6. The releaseorthemachine from its position shown in Fig.2, by the depression of keyG, serves to release the'driving mechanism thereof to feed the checkstrip forward by the conjoint action of feed cam'll and counter drum 10.The suitable engravin' upon drum 13 is also impressed at that time. 'Theimpression of the amount and the designation G by the printing drum andthe platen is executed after nearly half a rotation of the curved disc'7, in the course of the machine cycle. In the subsequent half cycle,arm 16 coacts through elements 40, 35, 3'7 and 39 to rock thecounterdrum 10 out of position, so that when feed cam 12 reaches its lowerposition, it has no structure to cooperate therewith to effect a feedingoperation. The position of operation of the der these elementsinoperative. .In the alternatelmode of operation by depressing key W,counter drum lo'and curved disc '7 which actuates the knife and platenare initially depressed, and registration isefiected without the issuingof any check strip, since even feed cam'll does not engage with thecounter drum. Also the counter structures, illustrated in Fig. 4 are notaffected during the machine operation by virtue ofthe rocking of tongues44 and 45 out of their path.'- In'the further alternate mode ofoperation for the issuing of two checks illustrated in Figffi, bythedepression of key Sp, counter drum 28 is rocked into an engagingposition with the printing drum 23, fixed with suitable engravings. KeySp also serves to rock element 40 out of engagement with arm 16, so thatcounter drum 10.

will not be rocked in the latter portion of the machinecycle, but willremain in position to cooperate with the second feed cam 12. Thisresults in the issue of a long check, adapted to be marked with desirednotations in addition to the check normally. issued bythe machine.

knife and platen is likewise lowered so as to ren- What'we claim as ourinvention and desire to 15 I. secureby LettersPatent, is:"-
